YVF2 series motors use squirrel-cage construction for reliable operation and easy maintenance. This series motors have a good cooling effect at any speed with separated axial-flow ventilator. This series motors can save energy and can be automatic controlled, driven by variable frequency inverters. If fitted with highly accurate sensors, this series motors can achieve highly accurate operation of closed loop. YVF2 series motors are suitable for various operation systems by which speed-regulation is needed, so they have wide applications in many industries, such as light industry, textile, chemistry, metallurgy, crane, machine tool and so on.
